Hi NFC, Thanks for the response. I have many other eMG80's out there that are working just great, I'm installing 2 more later on this month. It's just these few that are having the problem. I have witnessed the offenders in action. Just yesterday I watched an LDP-7024 light up with all three colors and the display read: REG. DENIED : 106, it also showed the date and time with the pickup, conf, and log soft key. I unplugged it then plugged it back in, it rebooted and worked fine for about 10 minutes then start acting up again, I can take another phone and plug it into the same jack (106) and it will start acting up after a few hours. This particular phone (106) is riding on new CAT5e cable. However, the rest of the sets are on CAT2 25 pair, but their fine, no problem. Also, all of the systems are running the same model of phone, no mix.

Do you think the cable could be the cause?
